Note the holes are offset. Orient themounts so the holes are away from

the channel walls.

STEP 1Using eight of the 11mm long screws, fasten two Dual Block Mounts per end of a Nine Hole U-Channel as shown. Note the orientation ofthe Dual Block Mounts in the straight-on view below. Because the holes are closer to one side than the other, the orientation matters.

Repeat this process on the other seven hole U-Channel.

STEP 2

Using sixteen of the 8mm long screws, fasten the Nine Hole U-Channels to the Seventeen Hole U-Channels as shown. A recomendedlocation is shown but the location you choose could be different based on your needs.

STEP 3

Using four 11mm long screws, fasten a Quad Block Pattern Mount to the face of a motor. Then slide a pinion bevel gear onto the shaft asshown. Tighten the pinch bolts for the gear gently as you will adjust the final spacing later on.

Repeat this step for each remaining motor.

STEP 4Using sixteen 11mm long screws, mount the motor assemblies from Step 3 into the chassis frame as shown.

Note the position is onehole past the third slot

from the end.

STEP 5Fasten a Hyper Hub (using four 11mm long screws) to one of the largerbevel gears.

Repeat this step for each remaining large bevel gear.

STEP 6

Attach a clamping collar flush on the end of a shaft. Slide a shimand then a bearing onto the shaft as shown.

Repeat this step for each remaining shaft.

Note: the clamping collarsrequire a 2.5mm hex key

whereas everything else in thiskit requires a 3mm hex key.

STEP 7Place one of the Bevel Gear Assemblies from Step 5 in the chassis frame as shown. Slide one of the Shaft Assemblies from Step 6 through the secondlarge (14mm) hole from th einside, and through your Step 5 assembly. Slide another bearing and shim onto the shaft. Make sure each bearing isproperly seated in its corresponding 14mm hole.

Repeat this step for each of the remaining shaft assemblies.

STEP 8Using four 22mm long screws (each with a washer), fasten a Hyper Hub to one of the mecanum wheels. The hub goes on the side with the deeperoffset of the wheel core such that it is completely within the wheel once mounted.

Repeat this step for each remaining wheel.

STEP 9Attach your wheel/hub assemblies from Step 8 to your chassis as shown. Aim to leave about a 1.25mm air gap between the wheels and thechannel. When seen from a top-down view, the rollers on the wheels should appear to point towards the middle of the chassis.

STEP 10You are now ready to adjust the mesh between the bevel gears. When they are alignedproperly, the back side of the gears are will line up with one-another and you should feela very small amount of movement between the two gears. The space between createswhat is known as backlash and allows the gears to operate smoothly and withoutunnecessary friction. A trick to set the gear mesh is to insert a thin piece of material(gum wrapper, plastic bag, piece of paper) between the gears, slide them together, andtighten them in place. Once tight, rotate the assembly to remove the material.

Repeat this step for each bevel gear set.

Pro TipWe've included plastic grommets that easily snap into the 14mmholes of U-Channel. Use these anywhere you are routing wiringthrough the channel. This prevents the wire jackets fromchaffing against the metal edge of the channel and adds apolished look to your chassis.
